Electric pressure washers are generally best for small jobs, such as cleaning cars, boats and patio furniture. Electric pressure washers generate less pressure than gas powered pressure washers, so unless the home you are pressure washing is small, it is best to use a gas powered pressure washer to get adequate cleaning power.
Check your nozzle for debris. Debris can pass through the system and settle in the nozzle. It is very important to remove the clog immediately because the resulting decrease in flow of pressure can cause damage to and/or ruin the pump in your pressure washer. To clear the debris, simply turn off and disconnect the gun. Either blow the debris out of the nozzle or use a thin piece of wire to clear the debris from the nozzle.
